Using TT Self-employed, I want to import all data from 2020 to 2021forms, as my situation will be almost identical. Is there a way to do that before actual numbers arrive

See this TurboTax support FAQ for transferring prior year tax data to the TurboTax online editions - https://ttlc.intuit.com/community/entering-importing/help/how-do-i-transfer-last-year-s-return-into-...

Are you using the Online version?  It just opened for 2021.  Did you use Turbo Tax for 2020?  When you log into your online account it should transfer from 2020.

When you start your 2021 tax return it will transfer information from 2020. But it transfers descriptive information such as the business name and address, business code, etc. It will not transfer the dollar amounts, such as income and expenses.

See the following FAQ for more information.

When transferring a .tax file, what information carries over to my return?

Correct ... even if every number is the same you still have to enter each one separately ... the prior year amounts will not carry forward just things like the assets and the expense categories.
