I filed my SEP IRA as a traditional IRA in 2016. How do I amend my 2016 return so I can file 2017 correctly?
For how to amend 2016, make selections for the type of software you used and follow the results (linked below).
If you filed a traditional IRA, you can delete your contribution under:
Deductions & Credits >>> I'll choose what I work on >>> Scroll down to the Retirement and Investments section >>> Click Update/Edit next to Traditional and Roth IRA Contributions >>> the box should be checked for the Traditional IRA and you can uncheck it >>> the next screen will ask if you want to delete your entry and you can say yes.
To enter your SEP contributions, head into:
Business tab and click Continue>>> I'll choose what I work on >>> Scroll down to the Less Common Business Situations section >>> Click Update next to Self-employed Retirement >>> Next, answer Yes and enter your pre-tax payroll contributions under Elective Deferrals and the other categories as applicable.
