1099b box 1f shows a $5 "Accrued Market Discount". Tried entering n forms & step-by-step, the answer opposite from the amount of gain/loss shown on the broker's 1099b.??

Market discount is the difference between what you paid for a bond, and the maturity redemption price.  If you bought a $1000 bond for $950, your market discount is $50.  This discount must be included in your income, as interest, either over the period you own the bond, or when it is sold.  In box 1f your broker is reporting the accrued amount of discount over the time you held the bond. TT will show it as interest income on Sch B (look and see if it's on that form), and then subtract the same amount from your gain on the sale, since it's already been reported elsewhere.  Hope this helps.

Thanks TaxLady.  That makes sense and TT is doing that for my Federal return.  However, when TT prepares my NJ state return (based on information in the Federal return), the accrued market discount is not being included in the "Taxable Interest Income"line and the accrued market discount is still being subtracted from my Schedule B gain on sale line. So, it seems like I'm under-reporting taxable income for my NJ state return.  It seems like this is a TT error!

Thanks,
Robert

I think you're right.  It sounds like TT is not carrying the Interest properly to the state.

I have this same situation but my discounts are significantly greater.  Apparently, this discount is counted as interest rather than a capital gain per this response.  This doesn't seem to logically make sense to me but were dealing with the IRS. 

 

The NJ tax site indicates that interest and cap gains on US treasuries is NJ Tax exempt.  Is this discount NJ tax exempt?  It should be if cap gains are intended to be NJ tax exempt.  How do I adjust for this in TT?  It  currently appears to be treated as NJ taxable...

Yes, if this discount is related to US treasury interest, it is non-taxable in NJ.  Here is how to report.

 

1. Open or continue your return.
2. Go to 1099-INT interest income. Click on this, it should take you to the section of your return
3. Select Yes on the screen Did you receive any investment income? then Continue.
   • If you see the screen Your investments & savings or Here's your 1099-INT info, select Add investments or Add another 1099-INT, then Continue.
4. On the next screen, select how you want to enter your Form 1099-INT- say you will type it in.
5. When you enter the discount, enter this in Box 3.
6. After entering this, there will be a section where you will select that NJ does not tax this interest. See screenshot below.
7. In reviewing your NJ state return, the amount of the tax exempt interest will appear on the  Int/Div WKS in line 2.  you do not need to make any additional adjustments.
