"Ráno viděla moje dcera tvůj dopis na stole."

Translation: In the morning, my daughter saw your letter on the desk.

My daughter saw your letter on the table this morning - isnt this ok?

We actually had almost the same, weren't you offered that one? The only difference in your sentence is "this morning" instead of "in the morning". Added.
