Maybe not. It depends.
When you enter itemized deductions such as mortgage interest/insurance, property taxes, medical expenses, charitable contributions, all of these items are added together. Unless the total of itemized deductions exceeds the standard deduction for your filing status, you would not see any change in tax due or refund. I will still encourage you to add the information to verify. If the result doesn't change, you do not need to submit the amendment.
If you have already submitted your return, at this point, you
cannot make any addition to your tax return.
You have
two options:
If your
return got rejected for any reasons, you can return to the program/account to edit the info
along with other changes. You do not need an amendment 1040-X.
If your
return has been accepted, please see the following :
You will have
to amend your return by filing a Form 1040X. You should not try to
amend your return until it has been fully processed and you have received
your refund or your payment has cleared. If by editing the information
does not change the refund or amount you owe, you do not need to submit the
amendment.
Amended
returns do not “catch up” to your original return and replace them; they
are processed as two separate returns.
Amended
returns have to be printed and filed by mail. It can take the IRS up to
12 weeks or longer to process them. If you are due a larger refund than
on your original return, your amended return should only show the difference
and you will receive a separate check for it. If you owe money on your
amended return, it will show only the new amount owed, you will have to mail a
check with the return.
