Pioneer AMT Tax-Free Municipal Fund 1099-DIV doesn't list individual state earnings but Tax Fact Sheet lists state percentages. Do I enter dollar value for my VA?

On one of the pagea following the main form, you only break out the exact $$ amount that was from VA bonds, (and any us territories).  But you have to calculate the exact $$ amount yourself....and assign the remaining to "More than one state"

example below for an NC resident.

Looks like you can do Puerto Rico and VA....and the remaining is "More than one state".

Unless the $$ amount in box 11 is large, it may not do much on your VA tax return...but worth a shot.
