USA Capital Loss in Trust

[NP Hiker]

My friend has received a final K-1 from her deceased father's estate's trust showing a long term capital loss carryover of over $40,000. This was for calander year 2011. Does she have to file an amended 2011 return? Also is she limited to claiming only the $3,000 LT Capital loss on Schedule D and then carry forward the excess to future years or is there some way to deduct the whole $40,000 in one year (2011 or 2012)? She had no other capital gains or losses.

Thanks NPH
