kfBrady,
You are not alone, I have exactly same problem with 2024 Turbo tax premium. Totals of RMDs and actual distributions are not properly calculated. The 1099-R that have actual distribution higher than RMD to cover rest of 1099-Rs don't used in total calculations and as a result form 5329 generated and additional taxation applied. I used "override" in 5329 and enter correct amounts. That removes additional tax penalty for not satisfying RMD.
The best way is wait until the bug will be fixed, or you can leave with 5329 overwritten lines 52a and 53a
