ENon-deductible (carries to Schedule K, line 16c — also reduces AAA)
0
Enter the full meals figure at A. The simulator applies the 50% limitation. Entering a pre-halved amount would produce a deduction of only 25%.
Notes
Line 19 must be supported by a statement. Itemise here rather than entering a single figure on the Deductions worksheet — the total carries across automatically.
Meals: enter only the deductible portion after the 50% limitation. The disallowed half is a non-deductible expense — report it on Schedule K, line 16c, where it also reduces AAA.
Do not put charitable contributions or the §179 deduction here. They are separately stated items on Schedule K and never reach page 1.

Diagnostics
Columns (b) previously taxed income and (c) accumulated earnings and profits are not in use. They apply only where the corporation was an S corporation before 1983 or has earnings from a period as a C corporation.
Schedule M-2 does not tie to Schedule L. On Form 1120-S these are tax accounts governing the taxability of distributions, not a reconciliation of retained earnings. Expect the balances to differ, and do not adjust either to make them agree.
