Form 941-X is the IRS form for correcting errors on a Form 941 you already filed. The IRS says to use a separate Form 941-X for each quarter that needs correction. To reuse your employer details on another 941-X, upload a completed one and a blank, then review every line.

irs.gov says to use Form 941-X to correct errors on a Form 941 that you previously filed. The instructions list what it can correct, among them wages, tips and other compensation, federal income tax withheld, taxable social security wages and tips, taxable Medicare wages and tips, and taxable wages and tips subject to Additional Medicare Tax withholding. The form says to use it to correct errors made on Form 941 or 941-SS. RepeatForm does not work out any correction.
The form says "Use a separate Form 941-X for each quarter that needs correction." At the top you check the quarter and enter the calendar year you are correcting, and the date you discovered the errors. Do not attach the form to Form 941 unless you are reclassifying workers, per the form; the instructions explain line 42.
Part 1 says to select only one process. Line 1, adjusted employment tax return, is for underreported amounts, and for overreported amounts if you want to use the adjustment process. Line 2, claim, is for overreported amounts only, to ask for a refund or abatement. The form says not to check line 2 if you are correcting any underreported amounts. The instructions explain which to choose; RepeatForm cannot.
The instructions say you may correct overreported taxes if you file Form 941-X within 3 years of the date Form 941 was filed or 2 years from the date you paid the tax reported on Form 941, whichever is later. You may correct underreported taxes if you file within 3 years of the date Form 941 was filed. For this purpose the instructions treat a Form 941 filed before April 15 of the following year as filed on April 15. See the instructions for their example. RepeatForm does not work out your dates.
The instructions say you can file Form 941-X electronically using Modernized e-File and that you're encouraged to file it electronically; they point to IRS.gov/EmploymentEfile. If you prefer paper, they give the mailing address. RepeatForm does not file anything: it prepares the PDF; e-filing is done in your own filing or payroll software or through a tax professional.
Upload a Form 941-X you completed and a blank one; RepeatForm carries the matching answers across; you review them, then preview the PDF before you export. Handy when you correct several quarters one after another, or prepare a 941-X for each of several clients.
Part 5 says you must complete all five pages and sign. The Form 941-X PDF has no signature or date field, so nothing is carried and both stay blank for you to complete by hand on the printed form. The instructions cover who may sign for each type of business.
The IRS revises Form 941-X from time to time. Carrying a prior copy into a new blank works for many answers, but some fields are renamed or moved and match only partly, so check every line on the new form in Review before you export.
Upload the two versions, check what matched, then inspect the finished PDF before paying.

Read the instructions for how the dates are counted; RepeatForm does not work them out.

You can reuse the employer details that stay the same, such as EIN, name and address. The quarter, year, process, corrected amounts and explanation belong to one correction, so enter them again and check every line on the new form in Review. Sign it by hand.
