Itemized deduction go on schedule A.
For 2018 - 2020 many taxpayers that itemized in the past will find that they can no longer itemize because the standard deduction has doubled so all of their itemized deduction s no longer exceed the standard deduction.
Only if all itemized deductions exceed the standard deduction will it be of benefit.
Not all itemized deductions count the full amount. Medical expenses are reduced by 7.5% of AGI so if your AGI is $30,000, for example, then only medical expenses more than $2,250 would be an itemized deduction.
The 2018 tax law also caps the total of Sales tax OR State and local income tax, Property (real estate and personal property) taxes at $10,000.
Mortgage interest on loans after Dec 16, 2017 may be limited.
The Mortgage must be secured by the property to qualify.
Interest on home equity loans and lines of credit are deductible only if the borrowed funds are used to buy, build, or substantially improve the taxpayer’s home that secures the loan.
You can check the actual amount of itemized deductions by using the Search Topics for "itemized deductions, choosing" (under "My Account, Tools" in the online versions). Click on "Change my deduction". That will display the actual amount of itemized deductions vs. the standard deduction. (Be sure to uncheck "Change my deduction" after checking it so you do not lock in the wrong deduction.

Are you using 2019 software? You cannot use the online program now for a 2019 return. Online is only for 2020 returns--no other year. You have to use desktop software for a 2019 return, so it has all of the forms and schedules you might need. Your 2019 return cannot be e-filed. It has to be printed, signed and mailed.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
Since you are filing a late 2019 return, the IRS will not have a 2019 AGI in the system for you. When the 2020 software asks for your 2019 AGI so that you can e-file 2020, use “zero.” If you cannot e-file by using zero then you will have to print, sign and mail your 2020 return.
