How can I avoid paying on these 1099cs I received after I filed? They say I owe $700 and I'm not going to pay

I filed with TurboTax, even bought tge protective plan. Then I received 2 1099Cs I had no idea about. Tries to amend taxes but it says I owe 700 and I'm packing up my apartment now to live on the streets. How is this possible?
