Hi there, I'm struggling to answer this question attached below.
As you can see I've made attempts to assign charges and change the bonds around but I feel like I may have misplaced the positive charge, and for the first two, I don't even know why ChemDraw doesn't let me add a negative charge to =O !!! would you say these are 3 different resonance structures?
If anyone can point out any mistakes or has any feedback of these resonance structures I would really appreciate it!
Kind regards,

It's a bit unclear to me but don't forget charge and atom position must be conserved in these.
Consider pushing a lone pair from the methoxy oxygen onto the carbonyl; or from the amine through the ring to the ester

How are you calculating the formal charge? Two of your structures are incorrect on one or more grounds. I think it would help if you always included lone pairs.
