Why when I entered box 12a D $2135, it doesn't show up as a credit on line 32 on my 1040. It did in previous years and gave me a credit ?

Code D indicates that you made elective deferrals to a 401(k), not contributions to an IRA.  Your employer already excluded this amount from the taxable amount shown in box 1 of your W-2; it does not get deducted a second time on your tax return.

If in past years you mistakenly entered W-2 box 12 code D amounts as IRA contributions, those tax returns are incorrect and you should amend them.

If you're asking about your IRA deduction, that's only if you put money into an IRA.

I did put the money in my IRA but it doesn't show as a credit

Code D on your W-2 is for a 401(k) contribution, which is a plan through your employer.
