After you file

If you did not get a distribution then do not report it.  Go ahead and file the return.

I am worried about a year from now, with getting a letter from IRS.

However you should get a printout for the year showing no distributions was made from the account and document that the issuer of the 1099R was in error and was going to correct.

 A letter from the issuer of the 1099R would greatly help, to show IRS if necessary.

If you did get a distribution from a Roth IRA it still gets reported on the return, just shows as not being taxable to you.
