I am the personal rep and the sole beneficiary of my late husband's estate worth only $900. Do I really have to file Form 1041 and send a K-1 to myself?

He died in Sept of 2014. I didn't file anything in 2015 because the estate had no value. In 2015 his estate received $900 from his employer and it was reported on a 1099-R for 2015.
