Is your only income from working for a company that gives you a paycheck and they take out taxes for you and also income from interest you earn from a savings account?
You can use turbo tax or print a 1040 form or possibly pick up a form at your library and hand write it by hand https://www.irs.gov/pub/irs-pdf/f1040.pdf
Look over the form I linked and see if you can answer everything. Most of the form you probably will be leaving blank if you just make income from payroll and interest.
Some communities have free help as mentioned above.
If your taxes are more complicated you might want to pay someone to do it. My guess is your taxes aren’t complicated.
What state are you in? You might have state and county tax too.
You will receive all of your documents from your company and banks by Jan 31.
