I called Turbotax this evening and was advised that there was no known issue related to T691!  They advise me to clear all the forms and re do them (which obviously didn’t work).

is there going to be an update??  I’ve been using Turbotax for decades, this is truly disappointing and many wasted hours.

@versi1 Your frustration is understandable. This will be resolved by April 14th. Thank you for your patience. 

Have all the issues for T691 been resolved by April 14? Is Version 00.01.73 Build 7007 068G26 the most current and free of bugs as far as T691 is concerned?

@pleinjeu Line 66 of T691 source is line 22100. 

This form is needed to calculate your Minimum tax carryover, and most carrying charges from line 22100 on certain investments (like interest expenses), are part of this calculation. If you need more details about this form, we invite you to consult this link:

Line 40427 – Minimum tax carryover
 

Thank you for choosing TurboTax.
