After you file

1. You have 3 years to file an amended return from the original due date. 

 

2.Since $11.71 probably will not have any effect on your tax return or very minimal, you do not have to file an amended return. The IRS would prefer to lose a little than pay for all the processing. If it is less than $25 tax liability, you don't have to file an amended return.
