Both my wife and I started taking Medicare Part B in 2023, with each of our premiums starting to be withheld in 2023. We file jointly. I could enter my total annual amount for Part B in the TTax section for entering SSA-1099 data without a problem. However my wife's adjacent box has a hard wired $0, and cannot be changed. Why? Is this entered elsewhere in TTax, or can spouse's Part B witholding amount not be used anywhere in our return??
There is a Supporting Details window causing the box with $0 preventing access. Put your cursor in that box and click on Edit at the top of the desktop program screen. Then click on Add Supporting Details. With the window open you can click on Remove the Supporting Details and enter the Medicare Part B premiums.
