@aragno - the deadline to submit a 2021 tax return to obtain a refund is April 17, 2025 - three years from the original deadline.
the deadline this week is to use the free file program for 2021 - that is all. Turbo Tax closed its 2021 efile system last month to prepare for 2022.
just so I understand, you are stating you NEVER received the 3rd stimuls payment, so there is $1400 sitting on Line 30..... if you ALREADY recceived the 3rd stimulus payment, Line 30 should be zero
figure a paper filed return will take up to 6 months to process. the IRS has been woefully behind on paper returns but is slowly catching up.
