A code G rollover is not cash distributed to you so it should not be on line 4.
A 1099-R with a code "1" only in box 7 indicated that the account is NOT a Roth. A code "B" is a distribution from a designated Roth (a 401(k) Roth) and might also have a code 1. A direct rollover of a designated Roth to a Roth IRA should have a code "H".
Box 5 indicates that the box 1 amount is your contributions. Are you sure that the box 7 code is not "1B", not just "1"?
