Thank you for your answer!
But, is it available with Turbo Tax?
I tried to amend it, but the turbo tax only gave me the 1040-X form for amending tax return.
Should I send tax-return documents first, and send 1040-X form after sending the tax-return?
As you replied me, it will be the best I mail my tax return without 1040-X (Amend tax return form).
