"...should i be concerned?"
Probably not. Line 14 (A Code) is simply your share of the tax-exempt interest of the trust/estate.
The figure on Line 14 (H Code), being negative, will result in a downward adjustment to your Net Investment Income Tax calculation on Form 8960 and you will not even be subject to the NIIT unless you are above the income threshold (e.g., modified adjusted gross income of $250,000 if married filing jointly, $200,000 if filing single).
