You can make two transactions spending the same output but one would get confirmed and one would be invalid since the inputs are spent. You can make as many transaction at any amount to the same address at the same time. Provided that the inputs are unspent and the transaction is valid.
Do you own the address(1BiLrgvfH41M4a3J31jACCP7C5tgUuUV5M)? If not, the double spend would be impossible to do. To give us the better understanding, it would be better to tell us which address(es) did you spend the 0.05BTC from.
yes I own the address it is one of my bitcoin core wallet addresses. I'm really not too sure how to check which address the 0.05 btc was sent from.
