I am filing an amended tax return as I did not take the QBI deduction last year although I was eligible. I went into the prior year tax file and selected to amend it. The only change I made is to take the QBI deduction. The amended return shows changes in AGI in column A "original amount reported or as previously adjusted (see instructions)" a gross up of income which flowed down column A resulting in a higher tax liability in this column. The tax has a notation that it is figured "QDCGTW". This tax liability is higher than the originally filled return that did not consider the QBI deduction.
Why is the program making these adjustments and what would it be grossing the AGI up for? Deductions from Schedule 1 (insurance and SE tax)? The amounts are similar but not exact.
Column C "Correct Amount" starts with AGI that agreed to the prior year tax return as originally filed and then is reduced by the appropriate deductions including QBI which flow down impacting taxable income and related income tax liability.
Other information in Column C related to prior year taxes withheld and estimated tax payments agree to the originally filled return. Some minor changes to refundable credits associated with the reduction income flowed through as well. The biggest change that I do not understand is on line 16 "total amount paid... with original return..." This amount does not agree to the prior year originally filled return and is grossed up somehow. Should I be manually overriding this data to reflect the amount that was due with the originally filled return? This results in a reduction of the amount to be refunded but makes more sense to me. What am I missing as I do not like to manually override information that was populated by the program
