Is 1500 calories a day too much for me?

Hi! I’m completely new to this CICO thing, I tried doing the 1200 calorie a day thing but would last one week and would binge so I’m looking to up my calories to 1500 a day. Im a 25 year old woman, I’m 5’4 and weigh 180 pounds. I work retail and walk a lot so I always end up with 15k-22k steps a day but walk around 8k steps a day on my days off. I’ve tried putting my stats into a calorie counting app but I don’t know what to choose activity wise (I was getting mixed results when googling it) so I’m kinda stuck trying to figure out how much to eat. Any advice is appreciated! Thank you!
