Hello all

So quick question here. I need to make a one time purchase using bitcoin, but I'm not able to set anything up with a bank account due to a nasty divorce involving financial lawyers and such so how do I go about sending funds to a bitcoin address?
I know I can purchase bitcoins at a bitcoin ATM, but what do I do after I have the printed out receipt with the QR code on it?
I'm stumped here folks so any insight would be greatly appreciated.
Thank you.
