Lacerte/PTO do have F.8990 but don't get too excited because it's only a dummy form - it has been for TY2018 and still is in the first release for TY2019 (unless there's any major programming update that hasn't yet been rolled out).  It is, therefore, not any different than you attaching a PDF to the return in PS.  But yes, F.461 is in Lacerte/PTO.
