How can I import Expenses from QuickBooks Online to TurboTax Premium (under 2 different Intuit logins)?

Greetings TurboTax Community,

I'm filing my taxes in TurboTax Premium. I manage the books of a Sole Proprietor/LLC in QuickBooks Premium.

However, both are under 2 different Intuit logins/emails.

My questions:

1) Despite hours of research I couldnt find a way to link these 2 together. I've attempted these instructions but not available Im guessing in QB Online: https://quickbooks.intuit.com/learn-support/en-us/help-article/taxation/send-quickbooks-self-employed-tax-info-turbotax/L5x490sqZ_US_en_US

If I need to upgrade my QB or TurboTax to benefit from such features I thought I could upgrade and pay when filing?

2) When I login to turbotax, I've asked whether I wanna go to Personal Taxes or Business Taxes (incl. Sole Prop)

I've started to input my 1099-NEC for income in TurboTax under Personal Taxes. Okay to keep doing so? Or I need to use the "Business Taxes" when I login to TurboTax?

My goal is to not have to enter my biz expenses by hand in TurboTax.

Have a great day and thanks for your inputs!
