Overstayed for four days in 2018, how do I pay the fine?

Hi,
I overstayed my welcome in Brazil last year with 94 days, 4 more than allowed. I wanted to visit Brazil again  later this year. How is it with the fine? I only see planes that arrive at 6am or 10pm in SP and I am worried that they will turn me back because the police will not be working? I was planning to pay my fine with a Brazilian friend in the next month or so. If I have the receipt that all is paid will I be good? Or is it too risky. Thanks for any help.

Immigration's and PF will be working. I arrived in May at 5:00 am from a trip and there were agents. There was no one at customs for declarations. I believe PF has an agreement with the cambio for any payments at GRU.
Receipt should work

Texan brazil is correct you should be fine.

Thank you guys. Does anyone here know how to create a new bank payment order for my fine? I remember that I once saw a link on this forum here but I can't find it again.
