It's your first year so i wouldn't be too hard on yourself/critical about where you put things.
I would leave them all where they are this year and plant everything else where it's suposed to go according to your plan.
Just try and stick to it as well as you can and the few you have in at the moment will make very little if any difference.
Crop rotation is good practice and aids in stopping neutrient depleation in the soil and pest build so don't worry and enjoy.
