This has been a sporadic issue for 2 tax seasons now, I don't think we've ever seen if its on Intuits end or if its something that happens with certain banks or types of banks.   

I had it happen quite a bit in the 2018 tax season, I cant remember if I saw any during this last season, but I know other people did.

Do you see any common denominator with the ones that showed they weren't accepted but actually were?

Were they all a certain bank or were they all credit unions or anything like that?
