I have a 1065 wtih 754 assets.. on the asset entry worksheet select code Z on the Type of asset. then scroll way down to the Additional Asset Details.. select Amortization for Deprecation type and the Recovery period.  That should propertly amortize it.  I am looking at the 2022 program right now, in Professional and it then should populate an expense in Box 13, Code W.  There may be one more tweak to the K-1 that you have to but this should get you started.
