I'm new to QuickBooks and I've recently uploaded and categorised a lot of past transactions. 

I've gone onto the Tax summary page, and some of these transactions are wrongly in the 'disallowable expense' category.

Oddly, this isn't consistent at all - For example, my Zoom subscription is sometimes in the disallowable section and sometimes in the allowable section! It's very odd. 

Is there a way to manually adjust whether it's allowable or disallowable? 

Thanks in advance.
