It's too early to file a 2019 Form 7004 because a business tax year beginning in 2019 has not yet ended and the IRS has not yet published the 2019 form. If you need to file Form 7004 for a business tax return for a fiscal year beginning in 2018 you should be using 2018 Form 7004 in 2018 TurboTax Business, not 2019 Form 7004 and not 2019 TurboTax.
