Deductions as a single member LLC - cash base accounting

[taxesformyson]

Can I just show a single line item for total expenses versus shoing categories like travel, meals, capital, legal fees etc.

You could, but in my opinion, your return would be more likely to be audited if you lumped all of the expenses together into a single entry.

I'm using the cash method of accounting.  I'm assuming everything purchase in 2019  'capital' is expensed in 2019.  Where do I enter this type of expense in TurboTax business?

Unless you incorporated the single member LLC is filed on a Sch C with the personal tax return ... you will not use the TT Business version for that ...  you use one of the personal tax programs.

"Everything purchased" may not be a "Capital" item  that can be expensed, some may need to be depreciated.  I highly recommended you seek local professional assistance to get this business started off correctly.  Mistakes can be costly down the road.
