@Opus 17 & @xmasbaby0
Thank you both for pointing me to the 'Transcripts' link. I was not aware of that. We will both keep checking that. Also, good to know that the envelopes may not even be opened for a month or more. I don't really care about the timing of the processing and eventual payment of the IRS '21,'22, '& '23 refunds due. I am well aware that the '20 refund is forfeited. I will check on the state links at a later time.
The main takeaway, is that the only "proof" we will be able to provide in the reasonable short term is that our returns are in the 'possession' of the IRS and State. Now we do not need to stress about waiting for our returns to show up on our two IRS account websites. We will just send the certified mail 'proof of delivery' info to her employer.
Big thanks,
Dave
