Sorry you can't install Turbo Tax on a Chromebook. You need a full Windows or Mac computer. You may need to go to a local tax place. Do you have access to a printer?
If you can't install the Desktop program or if you have a simple return and want to file for free, you can fill out the blank IRS forms by hand. Here are some basic forms…..
Here is the IRS 2024 Form 1040
https://www.irs.gov/pub/irs-prior/f1040--2024.pdf
or if you want bigger type use 1040SR for Seniors,
https://www.irs.gov/pub/irs-prior/f1040s--2024.pdf
And 2024 Instructions
https://www.irs.gov/pub/irs-prior/i1040gi--2024.pdf
Sch 1 : https://www.irs.gov/pub/irs-prior/f1040s1--2024.pdf
Sch 2 : https://www.irs.gov/pub/irs-prior/f1040s2--2024.pdf
Sch 3 : https://www.irs.gov/pub/irs-prior/f1040s3--2024.pdf
Then when you do file 2025 enter 0 for the 2024 AGI since you are filing 2024 late.
