A couple of years ago Box 5 on the SSA-1099 would be populated and then would disappear. In the last 3 days this issue seems to have resurfaced. I've had 4 SSA-1099's that I populated and the information is no longer there.
I just got off the phone with support. This is a known issue that they are "working on" I am holding off filing any people with Social Security since the last time this happened you would finalize a return, file it and at a later date discover it had dropped Box 5 on the SSA-1099
