Thank you for coming back to this thread, sky.
I am sharing some insights about the 2-step verification code sent to your old number.
Since you mentioned that you already updated your number in your Intuit Account and deleted the old one, I recommend contacting your bank or your financial institution to update your number with them as well. This will enable you to use the updated number to connect your bank to QuickBooks Online.
Furthermore, I'm adding this helpful article for more insights into managing your business information: Change your business name, contact info, or EIN in QuickBooks Online.
Come back to this post if you have further concerns and follow-up questions about managing your Intuit Account. I'll be here to lend a helping hand. Have a good one!
