How do I talk to tech support? You just keep sending me to links telling me how to do something I just explained to you I did. IE:  I said I wrote the extra amount off in the receiveed payments window. I think that would imply I know how to do it. 

Please, tell me why a discount entered that way is showing tax collected and due on my current sales tax liablility when the original date of the actual part the customer paid(250 of a 400invoice) is in August of 2018.

Sales tax was paid on that amount at that time.

Well I already told you why it and what is showing up now. The discounted amount of $150 is showing up because I wrote it off in Dec 2019. That amount of tax it says has been collected and is payable now is being calculated on the discount. That should not be there.

Telling me it shouldn't be there doesn't help when I am asking why it's there implying its not supposed to be.
