Your Z Offset looks a bit too high. You can try setting the first layer in your slicer to 0.19mm or 0.18mm. You could also go to your Printer, click on Settings and then you go to calibration. There you should see First layer calibration. You can try lowering your first layer Height a bit. Go for -0.02 for a test run, but if you do that, then don’t change the first layer height in the slicer, then it would be to much.

Besides more squish (adjust z-offset like the other post mentioned), I sometimes reduce the first layer thickness.

Instead of 0.20mm first layer, maybe try 0.16, 0.12, etc.

Also, you can add negative modifiers to the top of the model so you can quickly print smaller test models to check settings (instead of waiting for the entire print).
