Retirement tax questions

Thanks for replying.  My real question is does this mean that if I want to contribute $8000 to a traditional IRA in 2024 I will not be able to deduct the contribution from taxable income if my income was greater than $143K (married filing jointly).  This seems crazy since I was never employed in 2024 with a company that offered a 401K plan.  I just had that last paycheck from 2023.   Thanks for your help.
