When signing to submit tax return it will not allow because does not recognize my first name ????
Did you return to the MY INFO tab and edit your information to review exactly what you entered ? If you entered so much as a space it will not match ... I would delete the first name and re enter it again. Then try efiling again in the FILE tab.
