Hello @db808
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. Are you trying to have all of the penalty enter the sales tax account? If so I would recommend putting in the sales tax penalty into it's own line then setting the category as the sales tax account. Make sure it's not taxable since it's already a tax then it should be showing in your account.If I'm not making too much sense or what I recommended doesn't work let us know and we'll take a second look.
Thanks,
Quicken Francisco
