Roth Conversion- deductible and nondeductible contributions

[MDF]

In April 2019 I converted my traditional IRA which had a balance of  ~$20K ($5500 nondeductible, $14.5 deductions contributions). I do not have other traditional IRAs (zero balance).  I made the $5500 nondeductible contribution for 2018 tax year and forgot to report it on the 2018 tax return.  I know I have to amend my 2018 return to report.  I have no previous nondeductible contributions. I assume that once I amend the 2018 tax return, I can report then report the roth conversion which has both deductible and nondeductible on the 2019 return in TT.  How do I report this type of roth conversion in TT?

Unless you deducted the 2018 contribution and there is not change to your 2018 tax then just mail a standalone 2018 8606 form - no need to amend.

Enter a 1099-R here:

Federal Taxes,
Wages & Income
(I'll choose what I work on - if that screen comes up)
Retirement Plans & Social Security,
IRA, 401(k), Pension Plan Withdrawals (1099-R).

OR Use the "Tools" menu (if online version left side) and then "Search Topics" for "1099-R" which will take you to the same place.

Be sure to choose which spouse the 1099-R is for if this is a joint tax return.
Be sure to pick the correct 1099-R type: Standard 1099-R, CSA-1099-R, CSF-1099-R, RRB-1099-R.

If this was a rollover or conversion, answer the question that you moved the money to another retirement account (can be the same account). The screen will open up with choices of where it was moved.

[NOTE: When you get to the "Your 1099-R Entries" screen where you can add another 1099-R, use "continue" to keep going as there are additional interview questions after that screen in most cases. You can always return as shown above.]

You will be asked of you had and tracked non-deductible contributions - say yes. The enter the amount from the last filed 8606 form line 14 if it did not transfer. Then enter the total value of any Traditional, SEP and SIMPLE IRA accounts that existed on December 31, 2019.

That will produce a new 8606 form with the taxable amount calculated on lines 6-15 and the remaining carry-forward basis on line 14.

NOTE: If there is an * next to line 15 then 6-15 will be blank and the calculations will be on the "Taxable IRA Distributions worksheet instead.
