We did Roth conversions of our entire traditional IRA balances in 2024 so owe a lot with this year's return(s). Turbotax is showing vouchers for estimated federal and state taxes to be paid in 2025. If we only have wages (with taxes withheld) and a pension (right now the entire amount being withheld for taxes since I set that up early in 2024 to pay for the Roth conversions) and a minimal amount of interest for 2025, and expect that the withheld taxes will cover our 2025 bills, do we still need to file estimated taxes? If so, can we change the amounts on the vouchers to zero, or (if we have a windfall later in the year), the taxes that would be due on the income earned that quarter, rather than 1/4 of the amount of what we currently owe for 2024 (which seems to be the default)?
