Yes, to e-file your extension form 4868, the IRS requires you to provide the Adjusted Gross Income (AGI) from your previous year's return as a form of identification for e-filing - it is not needed to mail your extension.
An incorrect AGI will result in a tax return rejection by the IRS and/or state tax agency.
