what does "Tax on excess accumulations in retirement account" in IRA Contributions Results mean?

[MaryK4]

If you contribute more to your retirement accounts that allowed, you must pay a 6% tax on the amount and any earnings that are attributable to the excess amount.

That’s because Turbo Tax thinks you didn’t take the full RMD from all your accounts.  Turbo Tax changed this year. When it asks about the RMD it is only asking for that one 1099R. You need to enter the amount in box 1 on that 1099R for the RMD, not the total RMD for all.
