Backstory:
I retired on 10/2020. No earned income since then.
My wife continues to work and earns enough to cover living expenses and both our Roth IRA max contribution limits.
We have continued to contribute the maximums to our individual Roth IRAs ever since 10/2020.
I recently remembered that you need to use "earned income" to fund an IRA, of which I have none. Then I learned of the Spousal IRA option, which we would qualify for since we do file taxes jointly.
My question is: Is the Spousal IRA a separate account type that I should have signed up for when I retired, or am I fine with my continued contributions to our current Roth accounts? The contributions come from our joint checking account.
Side note: I did sell ~$28k of stock in 2021 from by taxable brokerage account, in case that counts for anything.
Thanks for any advice you may have!
