Turbotax gave you a dumb answer. an ss-8 is used by the IRS to determine if you are an employee or independent contractor. if you were an employee you should have gotten a form w-2 from the company. since they didn't give you one the form to file with your return was Form 4852.
this may still cause problems since the IRS wants you to first call them so they can contact the employer
from form 4852
You must take the following steps before filing Form 4852
• Attempt to get your Form W-2, Form W-2c, or Form 1099-R (original or corrected) from your employer or payer before contacting the IRS or filing Form 4852. You did this by contacting them and ask for your tax form.
• If you don’t receive the missing or corrected form from your employer or payer by the end of February, you may call the IRS at 800-829-1040 for assistance. You must provide your name, address (including ZIP code), phone number, social security number, and dates of employment. You must also provide your employer’s or payer’s name, address (including ZIP code), and phone number. The IRS will contact your employer or payer and request the missing form. The IRS will also send you a Form 4852. If you don’t receive the missing form in
sufficient time to file your income tax return timely, you may use the Form 4852 that the IRS sent you to file with your return.

i suggest you mail in your return and attach a statement with as much info as you can provide about your employer and the fact they are now out of business. sign and date the statement. include something like the name of the person you talked to and that they informed you that the company did not file its payroll tax returns including w-2's. include your dates of employment.
good luck
