Just got another 1099-R from PBGC today, it looks like it's for the balance of what I received. Have to do the math but I think the two added together will be the correct total. The "corrected" box was not checked. Still going to wait and call their help line after the 31st, I don't know if having two 1099-R's from them is going to be a problem with the IRS. I use Turbotax so I guess I can just enter both of them and it should be OK. I was out on Medical from my current flying job for all of 2018 so my taxes are going to be pretty easy otherwise.
