Please help!  I am very tech challenged and was figuring out multi sig on my own to place an order on a darknet marketplace last night. In the process I prematurely sent $100 of BTC to the compressed version of my address. When I was placing my order, the market asked me to send BTC to the other version of my address. Now my BTC is floating around in space or something, but still at an address associated with my account. Is there a way to retrieve it?
My address (compressed) that I sent it to is:
12X3ZrbDhY3norV3HcQaC5ASsrwipmk1Z
It was supposed to go to the regular address that was generated which is:
1MSfcqR5wbNhqypauTksf6nbWyrEBiRh6
I can give you private and public keys too if you need. Thanks!!
