overthinking…AGAIN!

My boss took off last week without notice. There is a policy in place here that I am not allowed to work unless my boss is there. Because of this and because it is out of my control as I intended to work the whole week, my boss told me they would write me a personal check for the amount i make in a week, which is $750 before taxes. I don’t know how much i would make after taxes as the accountant here figures all of that out, so that is why i just gave her the full amount of $750 for the week. Should I have included the taxes? I don’t know why I feel guilty about giving my boss the amount I make before taxes. I feel like i should’ve added that in, but I’m not sure the calculations of all that. Like, it almost feels like i’m stealing. Please let me know if i’m overreacting or not.
