Where do I find Schedule a for 2018 return filed?

If it's giving you the Standard Deduction and you can't see schedule A, 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.

If you have filed a return where you itemized deductions and you want to view a copy of the Schedule A, here's how you get a PDF copy of your return.
