Do I get the unemployment tax relief approved 03-11-2021 when I already filed? Will you charge to e-file an Amend on 03-25-2021? I paid TurboTax for the regular return.

There is no charge to amend a tax return.  There will be more information after the IRS gives guidance on how this unemployment compensation exclusion is going to be handled going forward.

After the legislation has passed Congress and after the President has signed the legislation and after the IRS has written the rules, regulations and procedures.  And after the IRS has changed any forms or schedules to accept the tax code changes.  And after the IRS has approved the changes in the TurboTax program that apply to the tax code changes, then it will be available for the users of the tax preparation software.

This can take anywhere from several weeks to several months before it becomes available.
