Sounds like they issued the 1099-R with a code G because they did not know you were going to skip straight to the ROTH in the conversion process and skip the Traditional IRA step completely. You can enter the taxable amount in box 2a and simply change the code in box 7 to a 7 and then the program will ask the "conversion" questions and properly report the taxable conversion on the return ... I highly doubt the IRS will ever question your wish to pay more in taxes.
