[The title of this thread has been edited from the original: How do I find items in square after synced to etsy store]

I have synced my etsy store to the square, now when I am at a show and a customer picks up a item and wants to pay for it how do I "ring that up" my items have a sku in my etsy store but I can't seem to find a particular item in the square system on my phone, I put in sku # when Im on the charge page and nothing. I see all my items and pictures if I scroll down but it will be really a pain if I have to go into each one and try to figure out if its the right item. I have many similar items so that's why I need the sku's. Also if I just enter a custom price and sell the item then later remove it from my etsy inventory I get charged for the original etsy listing and then again for what would be deemed a non listed item. I am new to all this and am trying to get it straight, my apologies for the dumb questions. Admittedly I am technologically challenged. Thanks for any !
