SOLVED!!
I found the issue. There was a strange, nondisplayable character on the form which did not show up on the regular screen.
I went directly to the form by clicking on "Forms" at top left, and edited the number there. I firstly deleted everything in the account number field on the form, including the nondisplayable character. I then entered the correct number into the forms account number field. Went back to the "EasyStep" screen by clicking "EasyStep" at tp left and continued processing my Efileing.
