Recently, I have started to use PETG as my new material, before that I had been using ABS. But I stopped using ABS because of the cracking. I have been printing a lot of calibration cubes and I thought I was ready to print a bigger piece. This is the result, it has small holes and empty lines in the walls. On the top, I don't know what happened.

I have a Tronxy cube x5 which I use together with Cura. I print in PETG at 230 °C.The print bed is set to 65 °C. I use a print cooling fan at 30 %. The layer height I set to 0.2 mm, the line width from the 0.3 mm nozzle. The Printing Speed is set to 20 mm/s for walls and 35 mm/s for infill. My retraction is 4 mm/off at 20 mm/s.

What do you recommend I do?

It looks like you have moisture in the filament. Also, Your hotend temperature may be too low. See Printing PETG in Material to use inside ultrasonic cleaner
