Wanting to build more muscle

So I’ve only been using MFP for less than two months and I’m within 2 lbs of my goal weight. I’m wondering if I want to build muscle mass should I stop eating at a deficit and focus more on my macros? Should I just eat somewhere in between maintenance and what I’m currently eating? I’m 5’11.5” 147 female and I know I need to become friends with the weights. TIA for input
