Google sheets - Copy rows and insert in another tab with fórumla and automated process [closed]

I searched the forum and did not find an answer to my question.

I need to automate a process and I don't know how, could you help me?

1. take the line: (C2:H2) add all cells with +1 until cell F2 reaches the number 60 and stop adding.

2. Save the result of this sum in another tab.(EXTRASOMA)

3. Repeat the process in line (C3:H3) and so on until you reach the last line.

This would be done once. when IMPORTHTML updates with a new line each month, it would do the process again.

Is it possible?

The only thing I managed to do was the sum formula, but I don't even know if it turned out very well:

=IFS(C2>=60;"";$F2>=60;"";$F2<60;C2+1)
