You can amend. But, If you took the standard deduction this won't make a difference.
If you took itemized deductions, or added all of your deductions because you wanted to see which was best for you, then you should go ahead and amend to find out if your refund increases.
To amend:
Log in, and click the blue Amend link in the bottom left side of the paragraph.
Click here for specific amending
instructions. 2017
NOTE: You MUST wait for
the original returns to be accepted or rejected before doing anything. All
amendments are required to be mailed.
If your return is rejected you can make the
needed changes then resubmit them by E-file.
If your return is accepted you MUST wait until
they have been fully processed and you have either received the original refund
or paid the original balance due before amending them.
