I've been having the same issue! Had a QBs from Support screen sharing with me and we tried all the things mentioned but it still gave us that same box asking if I entered the information correctly, which I did. Nothing worked and this  isn't the only time its happened lately ! The customer ended up paying online by clicking on the invoice. Guess what, the same Exact information I was trying to enter is what she used and it went through for her but not me. This is getting Very Frustrating !
