You need to call TSP. They screwed up a LOT of peoples 1099"s. There is a Facebook group call Thrift Savings Plan (TSP). It is being talked about profusely . With the new TSP site and the group that took it over they screwed up SO MUCH STUFF. I highly encourage you to join that group and see what they are saying to do.
I retired from the VAMC in 05/2021. It's a really good group.
