2025 IRA contribution

[shapop]

Hi.  I am retired and took 30,000 out of my IRA in 2025. Taxes were paid during the distribution and it was put into a CD. I was trying to reduce my taxes due so I was playing around with the 2025 IRS contributions.  TT asks it it is from previous IRA distributions and I check no, but when I put in the 2025 total IRA contributions, it decreases my taxes due UNTIL TT asks if the contributions were deposited in 2026 versus 2025 then it increases taxes due dramatically. I don't understand. I thought contributions before 4/15/26 were for 2025. Why is TT asking me if they were deposited in 2026 and why should it matter? HELP!

You posted that you are retired. Did you have earned income in 2025? If not, then you can’t contribute to an IRA.
