Just keep a paper copy of what you filed.

No one at IRS is going to look at each one, whether the return is e-filed or paper-filed.

The paper was sold out before the first copy was printed.

Last year was the first year ever that more people filed an electronic file than a paper return.

Last year more individual returns were filed electronically than by paper and more refunds were returned through direct deposit than through the mail.

You can't really copy what I do because I don't do anything.
