Tax Table Or Tax Computation Worksheet

Question: 2008 tax amended form. Help needed!?
I have two W2’s. I filed one and didn’t file the other. Nor did I file any state taxes (long story). Anyways, for the amended form (1040X) line 6( Tax Liability) ask you to use a method to calculate this tax, either a tax table or tax computation worksheet.
I dont have a line 43 or line 44 listed on my original tax return. How am I to figure this out. I dont recall having any tax liability ???
Answer: If your income on line 5C is greater than 0, then you have a tax liability for line 6C. Look it up in the 1040A instruction book.
