2019 Excess IRA contribution refund with Interests and Tax withholding

In 2019 we made an excess of $6,000 to my wife IRA.

In 2020 we requested a refund. We received the $6K plus:

  *  $14.55 State taxe were withheld

  *  $193.65 interest were disbursed to us.

It seems any 1099 form showing this refund will come in May after our filling.

We will not declare the $6K IRA contriburion in our 2019 tax form since we got it back in Feb 2020

Our questions about this are:

 1. Should the State tax payment be included in the 2019 declaration or in the next 2020 declaration?

 2. Should the $193.65 interest be declared in the 2019 schedule B or in the 2020 schedule B as interest?
