Self employed fee clitch

my 2019 income is bigger than 2020,( 2020 I have no w-2 income at all), so I selected 2019 and it gave me a bigger refund, but when I tried to add a $500 side job freelance photo work to see what would happen Turbox is now charging me as "self employed" fee of over $100 plus state.  I cannot "clear and start over" because  I "registered" but the summary says it's free with zero fee but again when I tried to delete the additional income and file it as regular is still list me as "self employed" and want to charge me.  Turbox tax is very confusing and clitchy.  Sorry my writing is bad.  Thankyou and stay safe
