Since it has been less the 60 days since the distribution from your own HSA account, you still have time to complete rollover of that distribution to another HSA account in your own name, avoiding tax and penalty on the distribution from your original HSA account. Other than spending the money on qualified medical expenses, a rollover is the only way to avoid the tax and penalty. You can open the account with any HSA custodian that allows individuals to open HSA accounts; there are a number that have very low fees and offer a variety of investments. Since you were not satisfied with the fees of the old HSA custodian, I would look elsewhere.
A return of mistaken distribution is something else, not involved
here. I think I misunderstood your question as indicating that you had
deposited the distribution from your HSA account into your wife's HSA
account, but now I see that that is not the case, so ignore my question
about a return of contribution.
