There are numbers in all three columns.  However, there is no change in taxable income.  it's zero all across.  There's no tax before or after amendment.  That's why I tried to take out the refund already received.  I was hoping it would process but get adjusted by IRS because they had already sent the refund.  I would have to add $351 of income to get a taxable income change.  I'm not sure that would even process.  I think I need a change in tax. I suppose I could put in enough to create $1 of tax and see what happens.
