Yes.
You should do the conversion promptly because you will be required to pay taxes on any gains that are made while the money is in the traditional IRA account when you do the conversion.
Vanguard has instructions here:

The process is easy enough as long as you keep track of how much you've contributed.
There is a process where you recharacterize it as a non-deductible contribution to a traditional IRA.
Just call them and they do everything for you. Takes 5 minutes
Thank you!
