Need help calculating True Strike attack and damage rolls

Should be an easy one, but here we go. Can someone help me calculate my True Strike rolls with a heavy crossbow?

• Dex: +1
• Prof Bonus: +2
• Spell Attack: +5
• Spell Modifier: +3
• Weapon: +1 heavy crossbow
• PC level: 3

From what I gather, the attack roll would be +6 (+5 spell mod plus +1 weapon mod), and the damage would be 1d10+6 (+5 spell mod plus +1 weapon mod). 

The attack modifier would be +6: +3 from your spellcasting ability modifier, +2 from your proficiency bonus, and +1 from the weapon.

The damage modifier would be 1d10+4: 1d10+1 from the weapon, +3 from your spellcasting ability modifier. (You don't add your proficiency bonus to damage rolls.)
