California Carryover Worksheet - Non-passive Loss No value in Line 10a for AMT

[zolbot]

My 2021 return was able to source my 2020 Turbo Tax to populate a lot of values.

One thing is missing, preventing me from moving forward and I'm not sure where to find it (if it even exists). 

My California Carryover Worksheet section for Loss Carryover (Non-passive) has a value on line 10a for the "Regular Tax" column, but the column for "AMT" is blank.

Any ideas where I might find this elusive number?
Or did Turbo Tax leave this field blank because the value was zero?

Any help with this would be much appreciated as I've been spinning my wheels the last 2 days trying to figure what to put there.

Thank you

After some digging, I found that my California Carryover Worksheet's (CCW) line 10a for Regular Tax value was sourced from my Form 4797 Sales of Business Property line 7.

Since I do have a Form 4797 AMT would it be safe to assume that the value for my CCW line 10b for AMT should come from the 4797 AMT line 7?

Thanks for any help
