Turbo Tax wants me to enter amounts for Accrued Market Discount from my 1099-B, but Fidelity did not report any of these amounts. Where is this amount located?

You might not have this form, it isn't common. Look for a Form 1099-OID in your Fidelity statement. If find the form, enter the information, it is your taxable income. Otherwise, put 0 there. 

I have Accrued Mkt Discount on 1099-B but not in the 1099 Int and TT is not telling me were to enter the info.

The Accrued Market Discount t in box 1f can be entered by checking the box I have more info to enter that I don't see here that is just below the box for Cost or other basis. Do not make an adjustment to the cost basis. You should post the 1099-INT exactly as you see it.
