Glad it worked.
Yes, this setting is in the customizer: TotalPress Options > Content > Posts > Content Layout you will see the setting called Padding.
This is where you can adjust the padding. You can also remove all the padding by using TotalPress Options > General > Layout > Container Layout – this is what the help icon will show you when you click on it:
Select “Separate Containers” to keep a space between all elements in the content area such as, articles, widgets, footer and so on. Select “One Container” to have no spaces between any of the elements.
Hope this helps.
Again, I apologize for forgetting to add that.
