Yes, you may be able to claim the American Opportunity Tax Credit (AOC) or the Lifetime Learning Credit (LLC) for the amount of tuition you paid.
Normally employers do not include Tuition Reimbursement in Box 1 of your W2. Because including the Tuition Reimbursement as Wage Income made it taxable income to you, you can kind of look at it as a "bonus" rather than a "reimbursement".
Since your employer included the Tuition Reimbursement in Box 1 of your W2, you can include 100% of the tuition you paid without reducing it for your employer's "reimbursement".
Usually, the AOC gives you the biggest tax credit and can be claimed up to 4 times per student.
