Retirement tax questions

Hi all

 

I am day trader. How do I deduct my laptop expense? I get 1099-B from robinhood, which gets reported on Sch D. I have completed an Sch C for my other business for which I get 1099-MISC. I don't know how expenses related to 1099-B get reported on Sch C. Can somesone please post a sample for simple tax return?

 

If opened LLC, is that a better option? how does that get reported. I do have LLC for my other business. I pretty much know how to file that. But its confusing for active day trader.'

 

Thanks in advance!!
