Yes, you would receive a 5498 from the new Roth in your name with the rollover amount in box 2.
Regarding the Roth IRA you opened in your wife's name, if you don't withdraw the money and close it, they should also issue a 5498, either as a contribution or a rollover. (If marked as a rollover because you told them so and they didn't verify it, that will trigger objections at the IRS since the IRS will know there are no plan assets in your wife's name that could be rolled over.)
