Turbotax did nothing wrong and the form is 8995. there is no IRS form 8895. The IRS is requesting a form that did not exist in 2018. the instructions for line 9 the QBI deduction line merely say to figure your QBI deduction using the worksheets in the 1040 instructions. it does not request any forms be submitted. i also had a QBI deduction for 2018 and no form or worksheets were submitted when I e-filed. the IRS never requested any support.
about all you can do is complete the worksheet in the instructions and explain when responding that the IRS never published the form requested for 2018.
the QBI deduction can become a lot more complicated because it can be limited if your taxable income is too high. you can also get the QBI deduction for any dividends specified as 199A/QBI dividends and there are a lot more items that can affect the deduction.
