Here are my thoughts on this:
- Based on your facts, you should have in fact completed form 7203 for tax years 2021 and 2022 since you received a non-dividend distribution.
- Form 7203 was created by the IRS to have a uniform schedule for maintaining shareholder stock / debt basis.
- As long as you did not take losses in excess of your stock basis, then I would not "amend" your tax return just to add that form.
- What I would recommend is that you do in fact complete a form 7203 for each year and have it available in case it is requested by the IRS; at this point it is already completed, you make a copy, send it in, and indicate since it is a new form you just overlooked it. This is all on the premise that you did not take losses in excess of your stock basis.
- After completing for form 7203 for 2021 and 2022, you now have an accurate beginning stock basis for Part 1 line 1 for 2023.
