I rolled over a traditional IRA to a ROTH IRA. the bank gave me a wrong Distribution Code for box 7 on form 1099-R. How do I fix this?

What code is present?  A rollover to a Roth IRA from a traditional IRA (a Roth conversion) would normally have code 2 or 7 but could also have code 1.

If the code is N or R, the transaction performed was a recharacterization of your traditional IRA contribution to make it a Roth IRA contribution instead, not a rollover.
