The IRS may catch this error and correct it or send a letter for you to respond. Based on the amount I would not file an amended return unless you are contacted by the IRS.
However, keep all the information handy in case you need to respond.
You don't need to file an amended return if you discover a simple math or clerical error on your return. The IRS can correct those types of mistakes on its own. An amended return isn't necessary if you forgot to attach a certain form or schedule to your return, either. The IRS will contact you by mail if they need additional information to fix these types of errors.
However, you should file an amended return if there's an issue that changes your filing status, income, deductions, or credits.
