If u file a W2 job how do you add a 1099 nec to pay taxes when you receive a refund. How long will anyone have to pay for

Question, how can you fix your return if you filed taxes from a W2 3.500 job. Also SSI income benefits 8.000, april 25 received a refund back this year 2023. Tax year 2022 forms  but  haven't amended it to file the $11,000 1099 contactor work . Turbo charge $150 to fix?  Still have to pay taxes.  Wonder if social security will find out if you file it and pay the taxes of $1300 or write off.how can fix this and how much time do that person have, without penalty? Why do you have to pay taxes for $11,000 that's nothing for the year. So the IRS and Social security work together in the system. Please explain because very uncomfortable 😣
