Will I be eligible for rapid refund on my 2020 return?

[DoninGA]

Sorry, there is no such thing a rapid refund. 

You will be able to electronically file your 2021 tax return and if everything is correct on your return and the IRS has no issues with its own processing procedures, you can expect to receive your federal tax refund within 21 days after the tax return is received and Accepted by the IRS.

If you are referring to a 2020 tax return, that tax return can only be printed and mailed, it cannot be e-filed.  The IRS may take 6 months or longer to process the mailed tax return.

If you have not filed your 2020 return---you are too late to use online software.   You can only use desktop software, and the return has to be mailed.

Online preparation and e-filing for 2018 and 2019 and 2020 is permanently closed.

To file a return for a prior tax year

 If you need to prepare a return for 2018, 2019 or 2020 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

You may also want to explore purchasing the software from various retailers such as Amazon, Costco, Best Buy, Walmart, Sam’s, etc.

Remember to prepare your state return as well—if you live in a state that has a state income tax.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.

Note:  The desktop software you need to prepare the prior year return must be installed/downloaded to a full PC or Mac.  It cannot be used on a mobile device.

If you are getting a refund, there is not a penalty for filing past the deadline.  If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.
