I see that Lacerte has input for this form, however does not generate it. The input may be found in Taxes>45 Other Taxes>Schedule J, Recapture, Other Taxes>Recapture Taxes>Recapture of federal mortgage subsidy (8828)

The help information for this box from F1 Help states:

Recapture Taxes Screen 45; Code 5

Enter the recapture of federal mortgage subsidy from a manually prepared Form 8828. The program includes this amount on the Total Tax line of Form 1040, page 2 with the description “FMSR”. Attach Form 8828 to the taxpayer's return.
