A code G with box 2a zero indicated a rollover to a Traditional IRA. If they issued a check then it should have been made out to your Traditional IRA and the IRA custodian should never have put it in a Roth.
However, all you can do at this point is to choose the "Substitute 1099-R" form type and enter exactally as your 1099-R is but make box 2a the same as box 1. Answer the rollover to a Roth IRA question yes.
Enter a statement that you are using a substitute because the money went to a Roth and not a Traditional IRA and the issuer refused to correct the 1099-R.
Unfortunately a tax return with a substitute 1099-R cannot be e-filed and must be printed and mailed.
