One method is to edit your text file in notepad++, you'll need to download that, then add the RF record to the end of the qb W2Text file.  The cell numbers are the character positions in the file.  Notepad++ will show you what the character count/position is on the line so you know how many zero fills and space to put in.  Base that on the maryland file format, RF record from the pdf, page 35

RF [removed]   <Add 496 spaces after the 1 in 61, "61" is the number of W2's I had, update for yours>
