I made a withdrawal from traditional IRA for $16,000 in 2018. I repaid the money into cash within the 60 day window. Do I report this IRA distribution? How do I report that it was repaid - so I don't pay the taxes and early withdrawal penalty?
Yes you report the distribution. You should have received a 1099-R. You enter it and then answer all the followup questions where you will indicate that you rolled it over within the 60 day time frame. To enter a 1099-R, type 1099-R in the search box and click on jump to 1099-R.
After you enter the 1099R you keep continuing through the screens and it will ask what you did with it. You check the box that says you rolled it over to another account even if you put it back in the same account.
Or what code is in box 7? And when you put it back did you replace any withholding taken out? If not the withholding becomes a distribution and taxable.
