Disabled and looking into side hustle

Hello,

I mentioned earlier that I am disabled on ssa.  I'm looking to start medical transcription as extra income. The companies I've looked into are willing to pay via PayPal ,venmo etc and wish to make you an independent contractor. How will that affect me going forward? I know that anything over $600.00 is considered taxable. So how would I file that 1099k along with my social security 1099 ? Would I need to pay into social security and Medicare? How would I go about setting aside the tax funds for the IRS?
