What forms hasn't the irs finalized and why

[Texas Roger]

Here is a list of forms and when they would be available: https://ttlc.intuit.com/questions/1908854-irs-forms-availability-table-for-turbotax-individual-perso...

The IRS doesn't tell anyone why the forms aren't finished. Once they are finished TurboTax and all the other software providers must load them into their tax software and then the IRS must approve the implementation.
