How to fill the 1095-a with 3 different self income sources?

You choose the business that has the 'plan' to provide insurance.  Ideally, that is the one with the most profit.

Looking at the titles of your businesses, at first glance all of them seem similar.  Is there a reason you are considering them as three separate businesses, rather than as one business?

Thanks for your reply! I worked as an Uber driver for one, and I also did some assistant jobs for a company part-time, the third one was my wife as a Doordash shopper.  So I put these 3 incomings into three parts.  Am I right to do this? 

thanks

Thanks for clarifying.  Yes, it sounds like they are three separate businesses so you did it correctly.

As I said before, it is ideal if you can 'link' it to the business with the highest profit.  If the business profit is more than the total of column A of your 1095-A, in most cases the health insurance will be fully deductible; depending on how much Premium Tax Credit you qualify for, your business profit can often be much lower and you can still take the full health insurance deduction. 

TurboTax does not allow you to apply it to more than one business.

Thank you very much!!!!!
