To see if your refund is higher by adding your daughter as a dependent, prepare an amended return to see the additional refund amount. You can cancel or undo the amendment if you decide not to amend.
Before you amend, see if your daughter qualifies as your dependent. Who can I claim as my dependent?
If you choose to amend, wait for the IRS to process your original return. See How to amend (change or correct) a return you already filed?
