You do not need to report anything on your tax return with regard to interest earned within the IRA account. It is only reported on your return when a distribution is taken out or when you have made additional contributions.
Did you get a 1099R for something? You don't report any interest or dividends, buys or sells, or any transactions inside the IRA. You only get a 1099R and report Distributions, withdrawals, rollovers or conversions to another account or if you didn't pay back a loan from it.
If you received a Form 1099-R, you received a distribution that needs to be reported on your tax return. What was done with that distribution determines the tax treatment applied to that distribution.
Did you receive a Form 1099-R?
If so, what is the code in box 7 of this Form 1099-R and is the IRA/SEP/SIMPLE box marked?
@dmertz I updated today and it doesn't look like they fixed the 1099R RMD process yet.
