The recharacterization results in you having made a traditional IRA contribution as of the date of the original Roth IRA contribution that you recharacterized, so the resulting traditional IRA contribution is required to have been reported on your 2022 tax return, either as deductible on line 20 of Schedule 1 or as nondeductible on line 1 of Form 8606. Since your 2022 tax return showed no traditional IRA contribution, you need to amend your 2022 tax return.
I question your assertion that you received a Form 5498 from Vanguard showing I contributed to a Traditional IRA . With regard to this contribution, you should have received from Vanguard a 2022 Form 5498 showing a Roth IRA contribution, no 2022 Form 5498 showing a traditional IRA contribution. The transfer to the traditional IRA would be shown as a recharacterization contribution on the 2023 Form 5498 that you have yet to receive from the traditional IRA.
