Help a confused young adult

I just got my stimulus check and I want to cash it and load the money on my card. It's a Money Network mastercard I got from my job to paid on. I can't figure out the limit as to how much I can put on it at once. I looked online and it gave me how much for a retail load and an ahc load. I have no clue what ahc is, but I assume the amount I call put on it would be under retail load since I always get to a retailer to put money on the card.

Can someone help me figure this out?
