Form 5227 cannot be e-filed (not programmed for efile by IRS). The Form 8948 should be generating with it to print for a preparer explanation of not efiling; however, it doesn't show up in the forms list. The Tax Return Options for Form 8948 says "when applicable", but it's not showing up in the forms list.
Remember that "when applicable" in Lacerte simply means, "when the inputs that exist are such that a form is calculated and now should appear in the return."
i.e. You will not get a Schedule A/itemized deductions and/or 8283/noncash until you have BOTH a) made entries on page25/itemized, page26/non-cash, pages10&13/wages & IRAs for withholding, *and* b) the sums of those numbers exceed the Standard Deduction.
If you make such entries, and then have reason to code100/delete this year a page10/W-2 that has a bunch of withholding so that the Standard is now higher... the Schedule A & 8283 are no longer 'applicable'--even though you have entries on pages25&26!--so they do not show as bold.
Have you made entries on page4.4/e-file miscellaneous, second section down, such that an 8948 is then generated? (Looks like code191/'software does not support the following items on the return', 'form' would be the one to use.)
