Subject: Re: What covered calls you got?
I happen to only have shares remaining in my taxable accounts and I really don’t want to have to sell and pay a ton of capital gains.

You realize that when you are assigned on a short call, you don't have to deliver the shares that have been in your account long-term. Instead, you can purchase new shares and deliver those. All my shares are in taxable accounts and I've done so a few times over the years with various holdings (to avoid incurring large capital gains taxes due immediately).
