Can't find the status of my refund for my Federal and State 2022 amended returns.

I sent in my 2022 Fed and CA return very early. It was accepted by both and I paid the IRS $1,772 and Calif FTB $278 by check. Both checks have cleared.  I then discovered I made mistakes on my original filing, and a few days ago filed amended returns with IRS and CA FTB by Turbo Tax.  According to Turbo Tax amended calculations, mistakes would result in me overpaying the IRS by $814 and getting a refund from Calif FTB of $344.  My question is this:  I tried accessing the "Where's my refund" webpage and it did not find any data for my return. How can I find out the status of both of may amended returns and how long will it take for me to receive the refunds I am owed?    Thanks in advance.
