This is simple enough to reproduce.
1. Take 2 separate IRAs, "a" with an RMD of $25,000, and "b" with an RMD of $20,000.
2. Actual withdrawn from a was $15,000
3. Actual withdrawn from b was $30,000
This is acceptable to the IRS since the total withdrawals >= the total calculated amount that needed to be taken.
When entering the 1099-R info for IRA "a", TT asks for the RMD amount. Upon entering the actual calculated RMD for "a", TT immediately generates the penalty. It doesn't seem to matter if I enter the 1099-R data for IRA "b" first which would indicate $10,000 more withdrawn than required, as soon as it sees the shortage for IRA "a", it slams the penalty on.
I got around this issue by entering the RMD amount to be the exact amount that was withdrawn instead of the calculated amount.
