Why cant I deduct interest on mortgage loan?I have always done so. We refied in 2017, only. We put 30,000 worth of windows in the home, and we cant deduct interest?

I refied for no money back.  I put $30.000 into windows, and now I can't deduct my interest?

The IRS lets you deduct your mortgage interest, but only if you itemize deductions. Revisit the mortgage interest section. You may have answered a question incorrectly. 

In addition to itemizing, these conditions must be met for mortgage interest to be deductible:

• The loan is secured, which means the lender has some kind of guarantee of payment, usually in the form of property. If a borrower defaults on payments, the lender can seize the property that’s securing the loan. If you’re buying or refinancing a home, especially if it’s your first home, the loan is usually secured by the home you’re buying or refinancing.
• The home with the secured loan must have sleeping, cooking, and toilet facilities.
• The debt can’t exceed $750,000 (or $1,000,000 if the loan was taken before December 16, 2017) in order to get the full deduction.
• You or someone on your tax return must have signed or co-signed the loan.
• If you rented out the home, you must have used the home more than 14 days during the tax year or 10% of the number of days you rented it out, whichever is greater.
