Why is the only deduction being subtracted from tax liability is student loan interest. The software does nothing for home interest, charitable giving (13000+), and other

[CatinaT1]

Student loan interest is an adjustment to income that happens prior to your tax being calculated. You can see more information here: Student loan interest 

Your home interest, charitable giving, etc are itemizable deductions.  

Once you have entered all your itemizable deductions, you choose to take either the standard deduction or itemizing deductions - whichever is greater.

The standard deductions for 2022 are: 

Single; Married Filing Separately - $12,950 

Married Filing Jointly; Qualifying Widow(er) - $25,900 

Head of Household - $19,400 

You would have to have itemized deductions greater than the standard deduction for your mortgage interest and charitable contributions to make a difference. 

   

You may benefit from itemizing your deductions on Schedule A if you:  

Do not qualify for the standard deduction, or the amount you can claim is limited,  

Had large out-of-pocket medical and dental expenses during the year,  

Paid interest and taxes on your home,  

Made large contributions to qualified charities, or  

Have total itemized deductions that are more than the standard deduction to which you otherwise are entitled.

Technically, student loan interest is an "adjustment to income". That is, it's an "above the line" deduction,  not subject to your having enough deductions to exceed the standard deduction.  That is, the student loan deduction is allowed in addition to the standard deduction.  Mortgagee interest, charitable giving, and others are only allowed instead of the standard deduction.
