Based on your description of why you got this money (essentially additional wages), LinaJ2020"s reply is the correct way to handle the 1099-Misc. It will have you pay the employee's share of FICA. You can avoid form SS-8 by selecting reason code H.
But your question was: how can I put it as simple income and be done with it
Enter the 1099-Misc
On the next screen Describe what the payment was for
On the next screen select "none of these apply"
On the next screen select "No it didn't involve work like my main job"
On the next screen select "I got it in 2020" ONLY
On the next screen select No, it didn't involve intent to earn money
TT will put the amount on line 8 of Schedule 1 as other income
