Edit a posed model for 3D printing v2.8?

I have a rigged and posed model I want to print. After posing from the standard T, there are a few “bunched up” verts that I want to fix in edit mode. In edit mode, the model goes back to the T. How do I lock the pose for editing?

Thanks

With the object selected, look on properties/modifiers and find the “armature” modifier. On the dropdown on the upper right corner of the modifier, select “Apply”.

Thanks very much
