Are you sure that it is in a Roth and not a Traditional IRA?
You should discuss this with the 401(K) administrator if they directed it to go to the wrong type of IRA.
However, It is doubtful that they will change it, but you need to talk with them anyway just to tell the IRS that you attempted to get them to correct it.
You can ignore the 1099-R and enter a 4852 substitute 1099-R exactly like the one you have but make box 2a the same as box 1. Enter an explanation statement that you are using a substitute because the rollover went to a Roth IRA and not a Traditional IRA so the box 2a should not have been zero. Then explain the steps you took to get the 401(k) administrator to issue a corrected 1099-R.
That should make it a taxable Roth conversion.
