"unclaimed" income & multistate income?

I live in Texas. My Dad died in Texas. Recently, an out of state relative suggested checking "unclaimed property" databases for forgotten money. I did so.

 

I found a couple of thousand in a forgotten interest-bearing account in Louisiana, where Dad grew up.

I attached my name, but I haven't made a claim for payout because I have sooo many questions.

 

1) Is this taxable income? Or an undeclared part of his original estate?

 

2) Is it "simple" to transfer? Or should I consult an attorney with multistate expertise?

 

Thanks for any help!
