I erroneously said an inherited ira account belonged to my husband and not me, but there doesn't seem to be a way to correct it. any suggestions?

Please go back to the retirement section:

1. Click on "Search" on the top right and type “1099-R”  
2. Click on “Jump to 1099-R”
3. On the "Here's your 1099-R info" screen select the pencil to edit the entry
4. On the "Who does this 1099-R belong to?" screen select who the IRA belongs to.
