One LLC ' 3 businesses ' how to file it on schedule C

If all of the businesses are under the same LLC, you can put it all on one Schedule C for simplicity.

Yes i have 2 dba have similiar business ' pressure wash/window cleaning share same receipt from lowes home depot etc.  Then 1 turo business for car rental share 1 receipt from autozone and oreilly.

Now my another questions : example in 1 receipt ... 10 items i bought ...... do i need to make sure to list and calculate seperately  each item i bought base on category ::::::expense- asset ' expense- supplies::::;; ... or i can write : lowes 1 year receipt window-pressure wash dba ?..... because they all 100% for business anyway..... 

An LLC is a disregarded entity for tax purposes.  It is a legal entity, but unless you elect S-Corp Status or have have employees, it doesn't mean anything for taxes.  When you have separate businesses, they should each be filed on a separate Schedule C.  So if you have three businesses, you would have three Schedules C.  If you're saying that you have a pressure washing business and a window cleaning business, those are similar enough that they could be considered as the same business and filed on the same schedule C.  the Turo car rental business definitely needs to be filed separately, on a separate Schedule C.  

As for your other question, I'm not quite sure what you are asking.  You don't need to list every receipt.  Your expenses should be summarized by expense type.  You can review the different types of expenses you might have and need to report by reviewing the self-employment  business expense section of TurboTax.  

Ok great so my hirarky will be scedule C- John doe LLC - windowcleaning/pressure wash dba income/expense  - rental car dba income expense  - christmas ligjht income-expense

Ah ok for last question ' ill make more details ; 

Example from 10  lowes receipt there 20 pressure wash machine as exp[product key removed]' 15 window cleaning expense -asset tools ' also there 10 pressure wash expense-supplies ' ...... can i just added all to 1 line as.  .....schedule - window/pressurewash/ expense- asset/  ... or i need to seperate it and sum it seperate ......

Thanks again

i might disagree if the 3 businesses are separate and distinct activities. it would depend on whether they all properly fall under the same business code.
