Thanks Geo, but still incomplete.
Let me clarify:
To report Eligible dividends from another corporation;
1.interview section go to >>Income source
2. >>Dividends received from other corporation "+"
3. Enter *Amount of dividends subject to Part IV tax received by corporation Dividend subject to part IV tax
choose
>Dividend subject to part IV tax
4. Enter amount
5. Then click + to enter another row,
6. "Portion of eligible dividend deductible per ITA 112/113"
7. Enter same amount as this second row.
This will now generate an Eligible dividend treatment, and calculate the ERDTOH correctly.
