@SvenH The IRS has yet to update the 2018 Schedule A and the 2018 Schedule A instructions for the PMI deduction which would be located on the 2018 Schedule A Line 8d.
IRS Schedule A (2018) - https://www.irs.gov/pub/irs-prior/f1040sa--2018.pdf
IRS Schedule A Instructions (2018) - https://www.irs.gov/pub/irs-prior/i1040sca--2018.pdf
Until the IRS updates the 2018 form and instructions, TurboTax cannot provide the 2018 schedule and instructions in the 2018 software, either for filing an original 2018 tax return or amending a 2018 tax return.
