How can I file my 2022 tax return? I didn't file last year due to going through cancer treatments

To complete and file a 2022 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the 2022 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2022 tax return can only be printed and mailed, it cannot be e-filed using TurboTax.

Sorry it's too,late to start a 2022 online return or use the mobile app, either on Turbo Tax or the IRS. And too late to efile 2022.

If you need to start 2022 you can buy the Desktop download here

You will need a full Windows or Mac to install it on.

If you have a simple return and want to file for free you can fill out the forms by hand. Here are some basic forms.....

Here is the 2022 1040 return

Don’t forget your state. And you will have to print and mail your returns. So be sure to attach copies of your W2s and any 1099s that have withholding on them. You have to mail federal and state in separate envelopes because they go to different places. Get a tracking number from the post office when you mail them for proof of filing.

Then when you file for 2023 you need to enter 0 for the 2022 AGI since you are filing 2022 late.
