In 2018 improvements were made to the interior of a building (QIP) which under the then TCJA was 39 Yr property, the 2018 tax return has already been filed.  I have not filed the 2019 return yet.  Under the CARES Act I want to 1.)  switch to 15 Yr property, and 2.) Claim bonus depreciation for the previous expenditure.

  Is DCN 244 the correct Automatic Change Request DCN number for both switch to 15 Yr and claiming bonus?  Is there anything tricky in completing this Form for QIP in Lacerte?
