For item 10, there are two fields, the first appears to be for appended totals not reported within the form itself. This would be used for corporate taxes paid that fall outside of the fields shown on this form.

An example of a standard filing of this form can be found here:
http://yokoichi.info/tax/1-1.html

With this example, we can see the second field being used for a standard calculation for corporate tax total.
The second field for line 10 is the totals from 4, 5, 7 and 9.

Later, for field 33, fields 4, 5, 7 and "externals from 10" are combined for the same total of 10,265,864.
If the main field was used for 10, and not the external, this would be doubled instead of the same.
