Also, there were some changes in ownership and a member of the LLC left.

For example, 

1/1/19 - 3/4/19 : $0 [technically 0, because LLC didn't begin until March?]

3/5/19 - 8/1/19 : $1000 [Owner left on 8/1/19]

8/2/19 - 12/31/19  : $0 [Since owner left on 8/1/19]

My other thought is that since the tax year starts on 1/1/19, then their should just be two periods. But then the percentage is off a little, since it adds the extra days before the company started.

Thank you!
