After you file

Here are the AOTC requirements:

The student must be the taxpayer, spouse, or a dependent claimed by the taxpayer. The student must meet all the following requirements to be eligible.

• The student has not already claimed the American Opportunity Credit in at least four prior tax years.

• The student had not completed the first four years of postsecondary undergraduate education before the tax year as determined by the educational institution.

• For at least one academic period beginning during the tax year, the student was enrolled at least half time in a program leading to a degree, certificate, or other recognized educational credential.

• The student had no federal or state felony conviction for possessing or distributing a controlled substance as of the end of the tax year.You state that you had completed over four years

If your school has determined that you have indeed completed the first four years of postsecondary education, then you cannot take this credit. However, it is possible that you will qualify for the Lifetime Learning Credit (LLC). There is no limit on the number of years you can use the LLC for undergraduate, graduate and professional degree courses, including ones to improve job skills. When you amend your return and answer the education questions correctly, TurboTax will automatically determine if you qualify to claim the LLC.

Here's how to amend your return:

You can amend returns that have been accepted by the IRS. If your return is pending, you won't be able to make any changes until it's accepted or rejected by the IRS. If you don't know your e-file status, we can help you check it. 

• Sign in to TurboTax.
• Scroll down to Your tax return & documents (you may need to select Show), select 2019 and then Amend (change) return. If you only see the option to amend 2018 or earlier, it's because you can't amend an unfiled 2019 return. Instead, just select Pick up where you left off, make your changes, and disregard the rest of these instructions.
• Select Amend using TurboTax Online.
• Carefully follow the instructions. Don't worry if your refund changes to $0. This is normal on amended returns.
• When finished, we'll give you instructions for printing and mailing your amended return, as amendments can't be e-filed.

Three weeks after mailing your amended return, you can start tracking it at the IRS Where's My Amended Return? tracking tool.  Please allow at least 16 weeks for the IRS to process your amended return.

Processing times for amended state returns vary from state to state. If it's been more than 12 weeks since you mailed your amended state return, and you haven't heard anything, we suggest you contact your state tax agency.
