Confirmed but not reflecting /decode?
The transaction has a lot of outputs. On of the outputs is the address you mentioned. The tx lookup in www.blockchain.info says, that 0.0579332 BTC was sent successfully with 2175 confirmations (as per today) to 17tmL8Jsa4Hv9ZVVwtKCgrpqr1TbaNxgMp. 

There is also a "return address", which transfers 57.68039601 BTC to a SegWit address (bc1qgukqed6kdae4hjgdz9cm7xhrp2mu39054mwa2m). So I assume the funds come from an exchange or similar institution. 

If you are the owner of the address 17tmL8Jsa4Hv9ZVVwtKCgrpqr1TbaNxgMp (aka: you have the private key for this address), then you own these funds, and can spend it.
