Unless it was an investment property (and did a 1031 exchange), the fact that you used the proceeds to purchase a new home doesn't matter for tax purposes. If the home was sold while you were single, you may qualify for a home sale exclusion if you lived in it 2 of the last 5 years.
If your home sale must be reported, then you can report your share of the sales price and expenses.
If all of the following apply, you don't need to report it.
You lived in the home as your main home for at 2 of the 5 years preceding the sale.
Your "net" profit from the sale is less than $250,000 ($500,000 if Married Filing Jointly).
You didn't take depreciation deduction on the home or use it for business during the time you owned it.
You didn't rent it out at any time that you owned it.
You didn’t receive a Form 1099-S.
Where to enter the sale of your home (if required) in TurboTax: While inside the software and working on your return, type sale of home in the Search at the top of the screen (you may see a magnifying glass there). There will be a popup that says Jump to sale of home. Select that to get to the general area.
You can deduct any interest, property taxes, and most mortgage insurance premiums that are reported on the Form 1098 Mortgage Interest statement. You can also deduct any interest or property taxes from the settlement statement that are not already reported on the Form 1098 and not "pre-paid" and held in escrow.
Additionally, you can deduct qualified points paid on a mortgage and qualified mortgage insurance premiums. (Points can also be called loan origination fees, maximum loan charges, discount points, or loan discount.)
