if the company you work for is treating you as an independent contractor they should have given you a 1099-MISC for 2019. if you are being treated as an employee you should have gotten a w-2. by 1/31/2020
your employer may be trying to pay you under the table hoping you don't report the income.
here's what you can do if you believe you should have gotten a w-2
-Call the IRS for assistance at [phone number removed]. When calling, be ready to give the following information:
Your name, address and Social Security number.
Your employer's name, address, city, state, zip code and telephone number, even if your employer has gone out of business.
Dates of employment.
An estimate of the wages you earned and the federal income tax withheld. Your estimate should be based on your final pay stub of the year or earnings statement, if available.
The IRS will call the employer and advise to send you your W-2.
as filing 2019 1040
If you can't get the W-2 form, you can prepare a form 4852 which is a substitute W-2 form that you can use to complete your tax return. Here is a link to IRS site that will explain how to complete it:
https://www.irs.gov/forms-pubs/about-form-4852
if you are an independent contractor you need to file schedule C and report the gross payments.
if your paystubs show withholding you are an employee, if not (no requirement for paystubs to show w/h but they usually do) perhaps you're being treated as an independent contractor.
if you are unsure of your status you can submit form SS-8 to the iRS

as an aside, your company may be very unhappy that you contacted the IRS. but you do have a legal obligation to file a tax return regardless of whether the company furnishes you with forms or not.
the IRS may penalize you but it is partly your fault for waiting so long. if you didn't receive the form by 2/28/2020 that's when you should have taken steps to ask your questions
