We are filing our taxes seperately, how can I enter only the amount I paid. My wife and I paid 50/50.

Instead of importing the information from the lender----if that is what you did----choose "I'll type it in myself" and then enter only the amount that you paid.

Why are you filing separate returns--usually the worst way to file, though?

If you were legally married at the end of 2022 your filing choices are married filing jointly or married filing separately.

Married Filing Jointly is usually better, even if one spouse had little or no income. When you file a joint return, you and your spouse will get the married filing jointly standard deduction of $25,900 (+$1400 for each spouse 65 or older)  You are eligible for more credits including education credits, earned income credit, child and dependent care credit, and a larger income limit to receive the child tax credit. 

If you choose to file married filing separately, both spouses have to file the same way—either you both itemize or you both use standard deduction. Your tax rate will be higher than on a joint return. Some of the special rules for filing separately include: you cannot get earned income credit, education credits, adoption credits, or deductions for student loan interest. A higher percent of your Social Security benefits may be taxable. Your limit for SALT (state and local taxes and sales tax) will be only $5000 per spouse. In many cases you will not be able to take the child and dependent care credit. The amount you can contribute to a retirement account will be affected. If you live in a community property state, you will be required to provide additional information regarding your spouse’s income. ( Community property states:  AZ, CA, ID, LA, NV, NM, TX, WA, WI)

 If  you are using online TurboTax to prepare your returns, you will need to prepare two separate returns and pay twice.

When filing separately you both must use either standard deduction or itemized deductions.  Property taxes paid are an itemized deduction so you enter the amount of taxes you paid on your return as an itemized deduction.  Your spouse enters the amount that they paid as an itemized deduction.  The total taxes paid between the two tax returns cannot be more than the actual taxes owed.
