I retired in 2021 and rolled my pre-tax 401k to a Rollover IRA, I only had a ROTH prior to retirement, no Traditional IRA. In 2021 I did move money from my Roll Over IRA to my ROTH, and realized a taxable event, which makes sense. My question is whether I need to enter my Rollover IRA value as of 12/31/2021 and if so, why do my taxes go up for entering this value. Also, my understanding is Form 5498 is informative only, and as such Vanguard is saying this form will not be available until after the tax filing date.
