State tax filing

 Since I don't know what percentage the beneficiary is, I used 50% for my playing around. Since I was using 50%, that meant that I had to double the amount on total amount of decedent pension. 

You had 100% went to one person which allowed the excess exclusion.

I changed it to 50% and got half the exclusion

Here is what you need to do:

1. Return to your state and go to the Retirement Distributions Summary.
2. Select Edit
3. Beneficiary? Select Yes
4. Decedents date of birth, enter
5. Total amount of decedent pension -if you are 50% beneficiary, double the amount you received. Enter whatever number works with your beneficiary percentage. Example: If you received $8,000 and there are 4 other beneficiaries, you received 20% of the total. The total to enter here would be $8,000 x 5 = $40,000.
6. Exclusions claimed on decedent return - enter zero
7. Your Percentage Share of Total Distribution - enter the percentage that is correct for your share of the inheritance. For example, above as one of 5 beneficiaries, enter 20% here.
