Is there a way My soon to be wife a college student and I been supporting her for 3+ years I heard there a way to claim her with her 1098 form how can i

I assume "I been supporting her for 3+ years" means that her parents no longer claim her as a dependent.

You can only claim an education credit, based on her 1098-T, if she qualifies as your dependent*. This means, in addition to supporting her, she must live with you all year and have less than $4700 of income, on her own.  In addition to the (up to) $2500 Tuition credit, you get the (up to) $500 Credit for "Other" dependents (non child).

If she does not qualify as anyone's dependent, and does not have enough income to normally file a tax return, and is over age 23, she may  qualify for a $1000 refundable credit on her own. 

The best way to get all that, and more,  woulda been to get married before 12-31-23. 

*There are two types of dependents, "Qualifying Children"(QC) and Other ("Qualifying Relative" in IRS parlance even though they don't have to actually be related). There is no income limit for a QC but there is an age limit and student status test, a relationship test and a residence test. Only a QC qualifies a taxpayer for the Earned Income Credit and the Child Tax Credit. The Other dependent (qualifying relative) credit is worth (up to) $500 per dependent and is non-refundable.  That is, it can only be used to reduce an actual tax liability.

A person can still be a Qualifying relative dependent, if not a Qualifying Child, if he meets the 6 tests for claiming a dependent:

1. Closely Related OR live with the taxpayer ALL year
2. His/her gross taxable income for the year must be less than $4700 (2023) ($4400 for 2022).
3. The taxpayer must have provided more than 1/2 his support

In either case:

4. He must be a US citizen or resident of the US, Canada or Mexico
5. He must not file a joint return with his spouse or be claiming a dependent of his own
6. He must not be the qualifying child of another taxpayer
