When I enter my IRA as a roth IRA my AGI does not go down but if I enter it as a traditional it does. For tuition assistance the AGI cannot be over $12,752.

UPDATED FOR TAX YEAR 2019

Contributions to a Roth IRA are not deductible on your tax return, just contributions to traditional IRA. 

Only contributions to a traditional IRA can be deducted on your return.  For 2019, the most that can be contributed to your traditional IRA generally is the smaller of the following amounts:

•  $6,000  ($7,000 if you are age 50 or older), or
• Your taxable compensation for the year.

Your traditional IRA contributions may be tax-deductible. The deduction may be limited if you or your spouse is covered by a retirement plan at work and your income exceeds certain levels.

• IRA Deduction if You ARE Covered by a Retirement Plan at Work
• IRA Deduction if You Are NOT Covered by a Retirement Plan at Work
