we can't see your returns. as to whether you should file '20 b/4 '19 it depends on whether or not there would be any items on '19 that would carry over/forward to '20. if so, then you should do '19 so the carryovers/carryforwards to '20 are correct and in the return. to e-file 20 use 0 (zero) for 2019 AGI
