The code-H Form 1099-R reports a rollover to a Roth IRA from a Roth account in a qualified retirement plan like a 401(k). The code-G Form 1099-R similarly reports a rollover to a traditional IRA from the traditional account in the qualified retirement plan. Those two make sense and must be reported on your tax return.
However, the code-R Form 1099-R is nonsensical if it appears as you say it does. A code-R Form 1099-R has nothing to do with any rollover. A code-R Form 1099-R can never have any amount in box 5. A Form 1099-R cannot have a zero in box 1 unless the form has the CORRECTED box marked to indicate that the transaction previously reported with code R never happened. A code-R Form 1099-R can never be issued by a qualified retirement plan like a 401(k) because it only applies to traditional or Roth IRAs.
