I think I didn't enter mortgage interest, leading TT to recommend that I take standard deduction instead of itemized. How can I find out?

[IreneS · Accepted solution]

UPDATED FOR TAX YEAR 2019

Remember that the standard deduction has increased for 2019--$12,200 if you're filing single and $24,400 if you're married filing jointly.

To find out if you entered mortgage interest (and you haven't filed your return yet), please follow these steps:

1. Go back into your return and click Federal > Deductions & Credits. 
2. In the Your Home section, click on the Start/Revisit box next to Mortgage Interest, Refinancing, and Insurance.
3. If you haven't entered any mortgage information yet, just proceed through the screens, entering the requested information on your first mortgage.  When finished, you will be brought to the Mortgage Deduction summary screen.
4. If you've already entered information on one loan, you will be brought to the Mortgage deduction summary screen.
   
5. Click the Edit box on the Mortgage deduction summary screen to check your entries.

If you've already filed or marked your return for mailing, you can get back into your return using these steps:

1. In TurboTax Online, sign into your account.
2. Scroll down to Your tax returns & documents.
3. Select 2019, and then select Add a State (you're not actually adding a state, this just gets you into the right menu).
