"I had to print my taxes out and mail them to the IRS is it too late for me to print them out and mail them to the IRS and get my return." not sure what you are asking because you say you've already mailed it to the IRS. do not file a second return. for 2018 through 2020 you're entitled to your refund. any refund for any prior year is lost if the return was not filed within 3 years of its due or if properly extended 3 years of the extended due date. the IRS is behind in processing returns. for 2020 it could take 6 months or more for a mailed return to be processed and the refund issued.. the IRS is also behind in processing some 2019 returns.
have you checked your refund status at the IRS website?
