A 2019 tax return can only be printed and mailed, it cannot be e-filed.
Print, sign, date and mail the tax return to the IRS. Include with the mailed return any forms W-2 and 1099 which have taxes withheld. Go to this IRS website for mailing addresses - https://www.irs.gov/filing/where-to-file-paper-tax-returns-with-or-without-a-payment
There are no penalties for filing a tax return after the due date if filing for a tax refund or there are no taxes owed.
christinajoylope,
Not sure which question you have: (a) how to print the 2019 return, or (b) whether if you mail the return it will be accepted.
I can answer (b): you still have another year to claim a 2019 refund by mailing in your return. Be sure to sign and date the signature area on page 2 of form 1040. You will need to attach copy B of any 2019 W-2's to the front of the return. Follow the mailing instructions on page 64 of the current form 1040 instructions https://www.irs.gov/pub/irs-pdf/i1040gi.pdf and use the appropriate mailing address from the back page 114.
