why i dont see the total on income on business snapshoton quickbooks online'

You'll want to ensure that the report period of the business snapshot is accurate, Mostafa-Fares.

If the transaction's date falls outside the selected date range, it won't be included in the total of the report. Here's a screenshot below for your visual reference:

Moreover, I recommend refreshing the browser you're using, logging out, and then logging back in to your account to refresh the account connection and resolve issues that occurred in your last session if the total income still doesn't show up.

If the issue persists, I suggest contacting our Phone Support Team for assistance. Thus, they view your account safely and investigate this issue further to find the possible root cause and a resolution.
