After you file

Go back to "Your xxxx Oregon taxes are ready for us to check" . . .

and choose the [Edit] box on Income.

 

Under "Here's the income that Oregon handles differently" 

[Revisit] Retirement / IRA and Pension Distribution Adjustments

 

Leave the "We received federal pension income for federal service" tickmark, ticked

(because that's not the way to fix this error)

Press [Continue] instead

 

and, "Review Federal Pension Benefits" (even if one mistakenly reported federal government service pension benefits.   Press [Continue]

 

and this is where one edits and deletes any non-blank values under the column Deduction.

Simply, [Edit]

and then blank out any entries in Pension Benefits, Date Work Began, Points earned . . . , Date Work Ended.

Blankity-blank it all.

 

That will blank out one's Federal Pension Income on one's Oregon taxes.
