SOLVED•by Intuit•51•Updated almost 2 years ago

Before you start:

  • Amended Form 1120-H returns can't be filed electronically using ProSeries software.
  • If you e-filed the original return, it must have an accepted acknowledgement to e-file the amended return.
  • If the original return was paper filed make sure original return and extension are not marked for e-file.
  • Before starting we recommend making a backup of the original return. See How to copy or backup client files using ProSeries

To generate the amended return for an 1120:

  1. Open the original return.
  2. If you are e-filing the amended return scroll down to Part VI - Electronic Filing Information. Check the Amended Return boxes for the Federal and any amended states.
  3. Press F6 to bring up Open Forms.
  4. Type X and select OK to open the 1120X.
  5. In the Amended Return Smart Worksheet, checkbox A. This freezes the amounts in Column A.
  1. Open the state return.
  2. Go to the Help menu and select Help Center.  Select Tax Help on the left, if necessary.
  3. Review the Tax Help Instructions to determine how to amend the state return. 
  4. In most cases, the state will have an amendment form. Check a box to freeze the original state amounts.  A column will then show the amounts that were originally reported on the state's main form.
  5. Go back to the federal return.
  1. Make the needed changes to the original forms, schedules, and worksheets.
  2. Open Form 1120X.

  6. Save the return.
