Tax Liability Line 6 Tax. Enter method used to figure tax (a code is mentioned QDCGTW) 

Line 6 Original (A) $10,069 Net Change (B) $910 Corrected  (C) $10,979

This is where the $910 is coming from and the only "Net Change". Rest are zeros.

How did a K-1 total loss of invested capital prompt a net change on Line 20 Amount you owe $910? 

K-1 Sch D: entered as Capital $1212  Loss -$1212 Total 0 

I tripled checked the numbers and boxes it's entered in. Ran Smart Check a few times. I'm confused.
