[Ignore the first paragraph of this post. See follow-up post below which provides a correction.]
It seems that you have mistakenly reported this as a nondeductible traditional IRA contribution for 2022 instead of for 2021, resulting in an incorrect 2022 Form 8606.
The Roth contribution and it's recharacterization were reportable on your 2021 tax return, not on your 2022 tax return, and the explanation included with the 2021 tax return. This is what the code R means. The result should have been a traditional IRA contribution on your 2021 tax return, either deductible on Schedule 1 line 20 or nondeductible on Form 8606 line 1. If nondeductible, the amount on line 14 of your 2021 Form 8606 carries forward to line 2 of your 2022 Form 1099-R to be used in calculating the taxable amount of your 2022 Roth conversion.
The Form 1099-R for the Roth conversion would have code 2 or code 7 depending on your age.
