Invoice numbering not automatically comes.by mistakenly comes a address , I have changed and turn custom number but still not works ,its picks a address

Welcome to the QuickBooks Community. I see your invoice numbering does not automatically come and mistakenly by address. I'll share some information and troubleshooting steps to help you rectify this issue.

As you have mentioned, even after turning on the custom number feature, it picks an address instead of the sequenced number. Are you perhaps using an integrated application for QuickBooks Online? It could be that due to the app's features, the mapping in your account is different. 

If this isn't the case, you can perform basic troubleshooting steps to see if it is a browser issue. Sometimes, your search engine's cache and cookies become corrupted, causing problems when accessing websites or opening files. To begin, open your QBO account in an incognito window. It will prevent the browser history from being saved. Please refer to the following keyboard shortcuts based on your browser type:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

If the private browsing session works, clear the browser's cache so the system can restart. This task is also possible in other supported, up-to-date browsers. 

I'm including these articles you may find useful in the future while working on a task in QuickBooks Online:

• Customise invoices, quotes, and sales receipts in QuickBooks Online.
• Common custom reports in QuickBooks Online.

Clearing the cache will reboot the system, allowing you to work with clearing the cache. It will also help you remove junk files that are slowing down your work.
