The code in box 7 is 7. The IRA/SEP/SIMPLE box is NOT checked.
I have resolved this problem by selecting the "None" radio button instead of "Other". I have been using Turbotax for eight consecutive years and I for each of those years I received this particular 1099-R and it was never an issue before this year (2024). I don't know why it suddenly became a problem but the software was giving me fits and preventing me from filing electronically but selecting the "None" radio button solved the problem. I have already filed my return. Thank you for offering your assistance.
