Update - Called PPS and they said no indication that EITC has ever been denied. 2019 refund was issued with no issues, and it also included EITC. One thing had changed on the 2020 tax return, though, and PPS agent wondered if it caused a problem.  Wife had always been listed as TP and her husband as spouse. For 2020, I switched them since husband is the only one working now. I was careful to change all the taxpayer/spouse indicators etc. I don't see why this would cause the issue, but it did. I redid the return with wife as TP as it was done in the past. It was accepted.
