State tax filing

Thanks for your response.  I appreciate it.  I did end up calling T. Rowe Price.  And Vanguard (who we also have some funds with).  And the support number for the office of the Maryland Comptroller.  TRP gave me the story that if there were any portion of their capital gains distribution to me attributable to U.S. government obligations that they would have included a footnote to that effect under each fund that had any.  I found that hard to believe, seeing as a number of my funds had dividends that did have a portion of such obligations, some significantly so.  The dividends are coming from the same funds as the capital gains.  It's just a pot of money.  If the dividends have them, it only makes sense (to me) that the capital gains would have some too.  Not zero.  But not one of my funds had a footnote.  At any rate, Vanguard's response made even less sense.  Their answer was that it was too complicated for them to compute, that there were too many factors to consider, and so they don't provide that information.  If that's the case, how can anyone ever fill in that line on the Maryland tax form, and why bother even having it?  Lastly, the Maryland Comptroller's office said what I expected them to say, which was to contact the mutual fund companies.  Which I told them I did and what their answers were.  They were as perplexed as I was.  Oh well, I can't just guess the number, so I'm leaving it blank and I'm moving on.
