Like mentioned by two other prominent members above, just edit the title with a word "resolved". I'd like to add that you better lock the thread too, to avoid further useless discussion and spam.

Regarding the situation with your coinbase, is it the exchange version you're using [and to receive your refund] or is it the wallet vesion? FAIK, though the exchange version is a custodial wallet [you didn't own the priv key] the wallet version is non-custodial, so unless I understand things wrongly [I didn't use coinbase at all] suppose you're using the wallet version [with its non-custodial nature] the basic principle of "not your key not your coin" doesn't apply as you have full control of the wallet through priv key.
This is my understanding of your wallet arrangement when you mentioned coinbase, that you're referring to your wallet, not your exchange account. In case you do use their exchange account instead of their wallet, due to its custodial property, I'll strongly suggest you to heed what examplens and AHOY said.
