You can confirm by clicking on the transaction link in the "Date" column. "Minting" just means adding the token to the blockchain, which is recorded on that transaction and visible on etherscan. "Null Address" in the "From" field just means no one owned it before you.
I purchased a NFT, transaction went through but its not in my collection and says its owned by "null address"

More on reddit.comTransferring a token to the NULL address
Rarible and OpenSea have blocked transferring a token to the NULL address and they refuse to talk about it or answer any questions… If i transfer a token from within the MetaMask app to the NULL address is it equal to burning a token and will it reflect on Rarible and OpenSea ??

In the transactions, it says that it was transferred to me. But it says the owner is "null address" and its not in my collection, does anybody know how I can fix this??

$100,000 Worth of Ethereum NFTs Destroyed by OpenSea Bug: ETH Dev - Decrypt
September 9, 2021 - Johnson told Decrypt that he hasn’t heard anything from OpenSea yet regarding potential compensation for NFTs lost due to the bug. Late Wednesday evening, the company issued a statement via Twitter, which appears to be its only public comment on the matter thus far. "We've reached out to the small number of users who were affected by the issue yesterday where sending an NFT to an ENS name sent it to the encoded version of the literal text (e.g. "OS.eth") instead of the associated address," the company tweeted.
